ABSTRACT

Objective:To study the special values of the time phases in liver enhancement scanning with multi-slices helical CT.Methods:The relationship between the image features and the time phases was retrospectively analyzed with 143 cases that underwent liver enhancement scanning with multi-slices helical CT.Results:The time phases of liver enhancement scanning included hepatic artery earlier phase,hepatic artery metaphase,hepatic artery advanced phase,hepatic portal venous phase,hepatic portal venous-hepatic venous phase,hepatic venous phase and lag period.Conclusion:The different image features have the special value in the different time phases when liver was scanned with multi-slices helical CT.They ought to be differently treated and used according to the different objectives of liver enhancement scanning.
